To rtl/ whom, t mfr/y con/cern:

Be it known that we, GERALD EDWARD HOL- LAND and HENRY JOHNSTON, subjects of the King ot' England, and residents ot Rangoon, Burma, India, have invented certain Improvements in Elevators `for Loading and Unloading Coal, &c., of which the following is a specification.

Our invention relates to an elevator which can be moved from place to place and by which coals or other tra,9,mentary materials can be rapidly delivered into a ships hold trom a truck or barge or raised from the hold and delivered into a truck or barge, as we shall describe, referring to the accoml'ianying drawings.

Iligure l is an elevation, partly in vertical section, showing the elevator according to our invention loading coals into a Vessel. Fig. 2 is a similar view showing two ot' the elevators raising coals from the hold of a deep vessel. Iig. 3 is a part transverse section of one side of the elevator. Fig. A is a side view of the elevator lowered upon its truck. Fig. shows two of the buckets in section to a larg'e scale.

.o is a truck which has liXed on it two triangular frames having sloping sides 71, supported by struts The sloping' sides 7) are formed as guides along which can slide blocks nl, forming the nuts ot' screws e, which can be turned in either direction by hand-gearf. In the blocks nl are bearings for a shat't to which are lixed at about their middle the sheet-metal sides /L ot' an elevator having at its ends bearings for pentagon wheels f/, round which passes a chain ot' buckets .7', which are jointed to side links l'ixed to l'langes t ot' the buckets. Between the sides /t are lixed face-plates m and back plates n, these lorming, with the sides t, casings which inclose the chain of buckets y'. At the bottoni oiI the elevator the sides of the casing are open to a hopper P and the easing on one side of the pentagon wheel at the top is open to a chute q, which may be covered by a grating to prevent entrance ot' fragments too large. An engine r, for which an electric motor might be substituted, is connected through suitable reducing-gear s to the shaft of the upper pentagon Wheel, causing' it to revolve in the direction of the arrow. Uoals or other fraguientary materials being shoveled or otherwise delivered into the hopper P, the buckets j as they travel through the hopper carry them up the elevator and deliver them to the chute q. By means oi' the screw e the shaft ot' the elevator can be swung' on this shaft to a position more or less inclined, in which it can be held by tackle or otherwise. When the apparatus is to be moved from place to place, it is lowered down onto the truck, as shown in Fig. l. The blocks d may be taken otll the screws e, leaving the elevator free to be raised or lowered and held in any position by tackle, as indicated in Fig. 2, where two or' the elevators are shown applied to raise coals from the hold of a deep vessel, the lower elevator feeding the upper one.

Having now particularly described and ascertained the natureot our said invention and in what manner the same is to be performed,

we declare what we claim isM l. An elevator comprising an endless chain oli buckets, a casing forming a continuous trunk l'or said chain of buckets and having an opening at each end thereof, a driving-motor mounted between the walls oi' the said trunk and means attached tothe casing for supporting the said elevator, substantially as described.

2. An elevator comprising an endless chain ot' buckets, a casing inclosing thcsanne, a driving-motor mounted upon the said casing within the same, a movable lrame and means for supporting the elevator on the movable frame and tilting' it to various working positions, substantially as described.

3. An elevator com prising an endless chain ol buckets, a casing forming a continuous trunk for said chain ot buckets and having an opening at each end thereof', a driving-motor mounted between the limbs of said trunk, a suspension-shalt secured to the easing above the centerot1 gravity ol the elevator, a frame having movable bearings lor said shaft, and means `t'or raising' and lowering said bearings to tilt the elevator, substantially as described.

al. The combination, in an elevator, of drums carried thereby, an endless chain ot' carriers passing over said drum, a motor situated in the space `formed by the bottoms oi the carriers and at the upper part of the elevator, and a suspending means consisting ol a shaft passingthrough the elevator aslight distance above the center thereof.

5. In combination with an elevator, a truck carrying the same, incline frames on said truck forming guides, blocks adapted to slide in said guides, a shaft passing through said elevator, a slight distance from the middle thereof, the ends of said shaft being held in the blocks, screws secured in said inclined frames longitudinally and passing through the blocks, and means for rotating the screws in one direction for raising one end of the i elevator or in the other direction for placing the elevator horizontally on the truck, substantially as described.

In witness whereof We have hereunto set our hands in the presence of two Witnesses.
